Most of the people getting it are prisoners because they have life in jail with no parole and the death penalty. And most of those people that go to jail is because they have sold drugs or committed murder and most of them are sentenced to death or Life in prison without parole.

In many cases especially with prisoners the 8th Amendment is against, for example they are given the life sentence without parole or the death sentence. In this Article it is talking about how a man named Dennis McGuire was sentenced to death in 1989 for rape and murder. And that when they had injected him the family found out the injection had other types of drugs and not the usual drugs it is suppose to have. But they also found put that Dennis' lawyer agreed of putting in the new drug. But before they were trying to find other ways to execute Dennis but they couldn't find any other execution. Many people especially suffer from the 8th amendment and most of them are prisoners and if the death sentence isn't in prison anymore more people are going to die in prison than die in an electrical chair or injection.
